MADRID, Jan 18 (Reuters) - Real Mallorca have signed Braga central defender Jose Carlos de Araujo Nunes on a three-and-a-half-year contract, the Primera Liga club said on Wednesday.

Nunes is the club's second reinforcement of the January transfer window after they signed Argentine striker Leonardo Pisculichi two weeks ago.

Hector Cuper's side are 18th in the 20-team Primera Liga.
